Technical Working Group on Fast Reactors (TWG-FR)

During the past 50 years the IAEA has been serving Member States interested in fast reactor research and technology development as a focal point for information exchange and collaborative research and technology development. Since 1967, the keystone of the Agency's activities in this field is the Technical Working Group on Fast Reactors (TWG-FR, originally called the International Working Group on Fast Reactors, IWG-FR).

The TWG-FR is a group of experts from interested Member States who meet every year and provide advice and support IAEA’s programme implementation, reflecting a global network of excellence and expertise in the area of advanced technologies and R&D for fast reactors and sub-critical hybrid systems (e.g. accelerator driven, and fusion/fission systems) for energy production and for utilization/transmutation of long-lived nuclides.

The TWG-FR offers the largest international forum for exchange and transfer of information in the areas of fast neutron systems. Through 50 years of functioning of the TWG-FR the IAEA has been supporting the Member States with a number of activities in the fields of safety, research and technology development, modelling and simulation, education and training, as well as fast reactor knowledge preservation.

The TWG-FR assists in formulating an international vision applicable, on the one hand side, to current and advanced fast reactors, and, on the other hand side, to sub-critical hybrid systems. The defining elements of this vision are:

  • Improved economics - fundamental to all successful technology advances;
  • Sustainable development - in which resource utilization and waste management strategies lead to advanced fuel cycles, including those based on the utilization of thorium;
  • Enhanced safety - maintaining current high levels with increased design simplification, and passive systems.

In this framework, the TWG-FR assists in defining and carrying out the Agency's activities in the field of nuclear power technology development for fast reactors in accordance with its Statute. It promotes the exchange of information on national and multi-national programmes and new developments and experience, with the goal to identify and review problems of importance and to stimulate and facilitate cooperation, development and practical application of fast reactors and sub-critical hybrid systems. Finally, the TWG-FR provides Member States with information about the current status and development trends of advanced technologies for fast neutron systems.

Many specific technologies are addressed in detail by other projects within the IAEA and in other international organizations. The TWG-FR keeps abreast of such work to avoid unproductive overlap and engages in cooperative activities with other projects where appropriate. The TWG-FR thus coordinates its activities with other IAEA projects, especially those of the Technical Working Group on Nuclear Fuel Cycle Options (TWG-NFCO), the International Project on Innovative Reactors and Fuel Cycle (INPRO), and the Department of Nuclear Safety, in interfacing areas, as well as with related activities of other international organizations (e.g. OECD/NEA, EC-JRC, ISTC, JINR).
